Mean annual survival rates for adult males and females were significantly associated with mean banding latitude (P &lt; 0.0001 and P &lt; 0.0004, respectively) and time period (P &lt; 0.0001 and P &lt; 0.001, respectively). Survival rates for both adult males and females were higher in the north and lower in the south. Because individuals from the northern regions migrate farther, the cost of migration in terms of survival was lower than some other factor(s) that may cause the gradient. The relationship between mean banding latitude and mean annual recovery rates was marginally significant for adult males (P = 0.043) but not for adult females (P = 0.183), suggesting that the gradient was not due to differential harvest pressure.

Simulation results indicated strong bias in correct classification rates when group sample sizes were small and when overlap among groups was high.

In a review of 60 published studies, we found that 57% of the articles presented results on classification rates, though few of them mentioned potential biases in their results.

The site is MacDougal Crater in the Sierra del Pinacate Reserve, Sonora, Mexico. Three sources of data have been used: a series of exactly matched photographs, begun in 1907; detailed permanent—plot maps, dating from 1959—1960; and an age—distribution analysis of a 170—yr—old population of Carnegiea gigantea. The crater vegetation is dominated by the woody perennials Cercidium microphyllum, Encelia farinosa, Prosopis sp., and Larrea tridentata, and the columnar cactus Carnegiea gigantea. Various populations of Larrea tridentata declined 50—90%, and Cercidium declined 60%, during the first half of this century with little or no recruitment since. Carnegiea numbers increased fourfold over the same period. A 200—fold increase in Prosopis in the playa—like crater center occurred in the early 1970s. Elsewhere on the crater floor, Encelia density increased markedly during the same period from insignificant levels in the early 1960s. Age distribution analysis for the Carnegiea population reveals three major establishment peaks during the 1790 period. Recruitment and morality records from the three sources of data are compared with regional climate records. The high mortality for some of the species was probably the result of the prolonged drought during 1936—1964. Establishment surges for some appear related to periods of unusually heavy precipitation during certain seasons. Clearly, desert communities are highly responsive to changes in the climate regime under which they grow.</span></p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.2307/1940301","usgsCitation":"Turner, R., 1990, Long-term vegetation change at a fully protected Sonoran Desert site: Ecology, v. 71, no. 2, p. 464-477, https://doi.org/10.2307/1940301.","productDescription":"14 p.","startPage":"464","endPage":"477","numberOfPages":"14","costCenters":[],"links":[{"id":223558,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Mexico","state":"Sonora","otherGeospatial":"MacDougal Crater, Sierra del Pinacate Reserve","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -113.63660909726968,\n              31.984767065523613\n            ],\n            [\n              -113.63660909726968,\n              31.96736017802877\n            ],\n            [\n              -113.61785155346885,\n              31.96736017802877\n            ],\n            [\n              -113.61785155346885,\n              31.984767065523613\n            ],\n            [\n              -113.63660909726968,\n              31.984767065523613\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"71","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a49b0e4b0c8380cd687f3","contributors":{"authors":[{"text":"Turner, Raymond M.","contributorId":7383,"corporation":false,"usgs":true,"family":"Turner","given":"Raymond M.","affiliations":[],"preferred":false,"id":372906,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Cultures of Achnanthes minutissima (Bacillariophyceae) were isolated from four sites along a longitudinal gradient of dissolved As within the study reach and were maintained at ambient dissolved‐As concentrations. Arsenic sorption‐rate constants for cell surfaces of these isolates were estimated as a function of dissolved arsenate and orthophosphate. All isolates sorbed orthophosphate preferentially over arsenate. Initial sorption of both arsenate and orthophosphate appeared to follow a first‐order equation within media formulations but did not adequately describe other observed effects among formulations or between isolates. Although estimated sorption‐rate constants increased slightly with increased dissolved arsenate concentration, algae isolated from a site with elevated dissolved As had a significantly slower rate of As uptake compared with the same species isolated from an uncontaminated site upstream.

Annual report 1989","docAbstract":"<p>The goal of this project is to compare net-pen rearing methods to traditional hatchery methods of rearing upriver bright fall chinook salmon (Oncorhvnchus tshawvtscha). Fish were reared at several densities in net pens at three Columbia River backwater sites during 1984-1987, and in a barrier net at one site during 1984-1986; methods included both fed and unfed treatments. The purpose of this report is to summarize the results obtained from the unfed treatments and the current return of adults from all fed treatments and the barrier net. Zooplankton were the primary food item of unfed fish. Fish reared in net pens utilized insects colonizing the nets as an additional food source, whereas those reared in the barrier net did not. Growth and production of fish reared in the unfed treatments were low. Instantaneous growth rates of unfed fish were much lower than those of the fed treatments and hatchery controls except when zooplankton densities were high and chironomid larvae were important in the diet of unfed fish reared in pens. Only fish in the barrier net treatment resulted in consistent net gains in growth and production over the rearing periods. Adult returns of fish from all fed and unfed treatments are lower than those of control fish reared at the hatchery. Returns appear to be inversely related to rearing density. Even though adult returns are lower than those of traditional hatchery methods, a cost-benefit analysis, as return data becomes more complete, may prove these methods to be an economical means of expanding current hatchery production, particularly if \"thinning\" releases were used.</p>","language":"English","publisher":"Bonneville Power Administration","publisherLocation":"Portland, OR","usgsCitation":"Beeman, J., and Novotny, J., 1990, Pen rearing and imprinting of fall Chinook salmon.

Multiple-regression models for estimation of length increments from initial length (at the start of the growing season) and condition indices had R<sup>2</sup> values of 0.63-0.76 for largemouth bass and 0.46-0.83 for white crappie. However, these models are not useful for indirect estimation ofgrowth rates because growth must be known (initial length equals length at capture minus estimated annual growth). Models based on length at capture and condition indices had R<sup>2</sup> values of 0.22-0.68 for largemouth bass and less than 0.45 for white crappie. The low precision of models based on length at capture indicates that condition provides a weak basis for indirect estimation of growth rates from Texas reservoirs sampled during autumn and, therefore, is unreliable for detection of size-related growth phenomena such as \"stockpiling\" (size specific, density-dependent growth depression). Direct estimates of growth rates based on back-calculations or tagging data seem necessary for reliable detection of size-related growth patterns for largemouth bass and white crappies from Texas reservoirs.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"North American Journal of Fisheries Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis","publisherLocation":"Philadelphia, PA","doi":"10.1577/1548-8675(1990)010<0434:EOCIFE>2.3.CO;2","collaboration":"Abstract has subscript/superscript to be fixed","usgsCitation":"Gutreuter, S., and Childress, W.M., 1990, Evaluation of condition indices for estimation of growth of largemouth bass and white crappie: North American Journal of Fisheries Management, v. 10, no. 4, p. 434-441, https://doi.org/10.1577/1548-8675(1990)010<0434:EOCIFE>2.3.CO;2.","productDescription":"8 p.","startPage":"434","endPage":"441","numberOfPages":"8","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":262595,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":262593,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/1548-8675(1990)010<0434:EOCIFE>2.3.CO;2"}],"volume":"10","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50dc9fd4e4b0d55926e3e6b5","contributors":{"authors":[{"text":"Gutreuter, Steve","contributorId":91437,"corporation":false,"usgs":true,"family":"Gutreuter","given":"Steve","affiliations":[],"preferred":false,"id":355468,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Childress, W.

However, agreement between nonhydric soils and nonhydric vegetation was not as high because most nonhydric soils lay adjacent to the wetland boundary.

These data show that public attitudes toward fire have changed significantly over the past two decades and that educating the public about fire and the managers' use of fire can have positive effects on behavior.

Maintenance of current control practices are unlikely to cause the development of TFM-resistant sea lamprey strains in the foreseeable future.","language":"English","publisher":"Great Lakes Fishery Commission","usgsCitation":"Scholefield, R., and Seelye, J., 1990, Resistance to 3-trifluoromethyl-4-nitrophenol (TFM) in sea lamprey: Technical Report 56, 15.","productDescription":"15","startPage":"0","endPage":"15","numberOfPages":"20","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":197404,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":91999,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://www.glfc.org/pubs/TechReports/Tr56.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae5e4b07f02db68a42b","contributors":{"authors":[{"text":"Scholefield, R.J.","contributorId":92641,"corporation":false,"usgs":true,"family":"Scholefield","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":326599,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Seelye, J.G.","contributorId":32861,"corporation":false,"usgs":true,"family":"Seelye","given":"J.G.","affiliations":[],"preferred":false,"id":326598,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Data regarding rates of return of females to natal or previously used nesting areas, nest site selection, and productivity of hens of different ages were collected from 1,166 nasal-marked and 2,142 banded hens of the 3 species and from 740 web-tagged mallard and gadwall young. In spring, yearling mallard and gadwall hens arrived at the breeding site later than older hens. Yearling gadwall hens initiated nesting about 1 week later than 2-year-old hens, and 2-year-old hens began nesting about 1 week later than hens older than 2 years. Gadwall hens older than 2 years also had a longer nesting season. </p>\n<br/>\n<p>Mallard and gadwall nest densities were highest in those cover types with the highest visual obstruction ratings. Cover preference in descending order of use was seeded nesting cover, odd areas, roadside, dry wetland, and canal-side. Blue-winged teal nest densities were highest in dry wetland and roadside. Nesting success was different among years, but not among cover types. There was no population increase at any cover type due to homing hens. Overall nesting success was 11, 10, and 23% for mallards, gadwalls, and blue-winged teal, respectively. Recruitment of fledged young was similar for yearling and adult mallard females. Production from yearling gadwall hens was a meager 0.2 young fledged/female.

Mallard and gadwall hens that nested successfully 1 year used the same cover type the next year. Successful returning mallard hens also nested closer to the previous nest site than unsuccessful hens. Twenty-nine percent of hatching year (HY) mallard females returned to the study area, and all of these returned as yearlings (second summer). Nine percent of HY gadwalls returned, approximately half as yearlings and the remainder as 2 year olds. </p>\n<br/>\n<p>Duckling survival from hatching until near fledging was 0.681 for mallards and 0.828 for gadwalls.

These efforts include planning and implementing reforestation activities that require the collection of natural resources and socioeconomic data, and the preparation of base maps. A combination of remote sensing, geographic information system and global positioning systems procedures are used in this study to meet these requirements.</p><p>Remote sensing techniques were used to provide base maps and to guide the compilation of vegetation resources maps. These techniques provided a rapid and efficient method for documenting available resources. Pocket‐sized global positioning system units were used to establish the location of field data collected for mapping and resource analysis. A microcomputer data management system tabulated and displayed the field data. The resulting system for data analysis, management, and planning has been adopted for the mapping and inventory of the Gum Belt of Sudan.</p>","language":"English","publisher":"Taylor and Francis","doi":"10.1080/10106049009354269","usgsCitation":"Falconer, A., Cross, M.D., and Orr, D.G., 1990, Procedures for woody vegetation surveys in the Kazgail rural council area, Kordofan, Sudan: Geocarto International, v. 5, no. 3, p. 49-58, https://doi.org/10.1080/10106049009354269.","productDescription":"10 p.","startPage":"49","endPage":"58","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":332950,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Sudan","volume":"5","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58776c59e4b0315b4c11ff5e","contributors":{"authors":[{"text":"Falconer, Allan","contributorId":178103,"corporation":false,"usgs":false,"family":"Falconer","given":"Allan","email":"","affiliations":[],"preferred":false,"id":657936,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cross, Matthew D.","contributorId":95378,"corporation":false,"usgs":true,"family":"Cross","given":"Matthew","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":657937,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Orr, Donald G.","contributorId":6454,"corporation":false,"usgs":true,"family":"Orr","given":"Donald","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":657938,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
